I said in one of my previous emails a few days ago that it seemed less attractive, at least compared to the posted patches, so I agree. The string-sharing approach reaches deeply into osd_client though. I have a *big* set of changes in the works for it - let me try to finish it, prepare the ground for reference-counting for object locators and ping you in couple of weeks? Discussing particulars like locking and RCU usage should be easier then.
